meme. coiin-cnixriva'roii. mm PARKHURRT, llainville, Kans. Filed June 1010. Serial No. 568,355.

To all whom it may concern:

Be it known that I, Wannna IAaniiuasr, a citizen of the United States, residing at Ilainville, in the county of Rooks and State of Kansas, have invented certain new and useful Improvements in Corn-Cultivators of which the following is a specification, re erence being had therein to the accompanying drawing,

This invention relates to cultivators, and has special reference to that class of cultivators in which a traveling vehicle is provided with a number of harrows and means for adjusting and guiding the barrows.

The invention has for its object to rovide an improved cultivator of this kin which may be used interchangeably to cultivate corn and repare the ground for wheat and to plant t 1e same. a The invention further has for its object to provide an improved cultivator which may be used to harrow the corn ground when the corn is high, and by means of whichthe barrows may be removed and drills secured to the ca tivator for sowing wheat.

With these and other objects in view, the invention consists in an improved cultivator extends down through a sleeve 13, secured to and depending from one of the longitudinal bars 1. the lower end of said shaft ll being mounted in a sleeve 14 located in one end of and secured to a rearwai-dly extending U-shaped strap member 15 in the rear ends of which is mounted n'giiide wheel 16.

17 indicates a foot. rest. for the driver's vertical rod 20, depending from the longitudinal rods 1. Bars 19 are supported intermediate of their ends by means of a vertical .22 of the rods 19, and at. its upper end to the cross portion of the U-shaped frame .2. livotc'tl to a sleeve 23 at each end of the horizontal portion of the U-shaped frame 2 is a lever arm having a short member 24 and u long member .24 the short member 2t being connected at one end by means of a chain 2.), with a whitlle tree .26, said chain extending under and part way around the grooved pulley 9. The long member 24' of the pivoted lever is connected by means of a chain 27 with a wliitlle tree 26, said cha'in 27 extending over grooved pulleys .28, mounted in brackets on each of the bars 1 On each of the outer sides of the cultivator and in details of construction thereof as hereinafter set forth and claimed.

Referring to the accompanying drawings: Figure 1 is a view in pers ective of a cultivator constructed in accorr ance with this in-! 'vention. Fig. 2 is an enlarged detail view partly in vertical section and broken away of the jointed portion of the connection of the steering wheel with the frame.

In carrying out the invention, the cultiq vator is formed with a frame. preferably; consisting of a pair of longitudinal bars orl rods 1 secured at their forward end to the] horizontal ortions 2 of a transverse nietallici U-sliapcd rame having de ending portions 3, with their lower ends iicnt laterally to form stub shafts 4, which extend through the hubs 4' of wheels 5 and through the parallel bars (1, said stubs t being secured by a. cotter pin 7' and the inner ends of said bars (i being integral with and projecting fromthe lower portion of each of the dc vending; portions 7 of a metallic U-shaped rauio 8. which is mounted on the longitudinal bars 1 by means of brackets 8' integral with saidi bars 1. Mounted in the forward end of each; of the pairs of bars 6 is a grooved pulley 0; for a purpose hereinafter set forth. Mounted l on the rear end of the longitudinal bars 1 i is a driver: seat 10, in front of which isi located the n r end at a rotar shaft Ill provided with? handle 12 la retich of that is located a liarrow 30, connected at its forward end by a wire link 31, engaging a pin !32, adapted to be adjustably mounted in one iof the holes 33 of a dependin portion 34 int the depending arm 4 of the U-shaped ifranie' 8. The liarrows are raised and lloweted by means of chains 35 connected at lone end with the barrows and at the other iend with downwardly inclined laterally proijeeting arms 36 of rotary shafts 37, each 3 having its hearings in a block 38 on U-shapcd frame 8. and in one of the brackets 8' on the 'lougitudinal bars 1. Each of the rotary shafts 37 has at its inner end a lever arm 38 which is connected by a rod 39 to the lower end of a lever arm 40, pivoted to the longitudinal arms 1, and having a pawl 40' engagin'na tooth segment 41 mounted on the longitudinal rods 1. -The lever arms 40 each have a handle 41' within reach of the driver. Located centrally beneath the cultivator is a harrow 42 connected by means of" chains 43 with the lower end of a lever 44 pivoted to the longitudinal bars 1, and having a pawl engaging a se mental rack bar 45', the u per end of the ever 44 having a handle 4 in reach of the driver. The

adjustable in 7. cngagin one of the holes 148 in the d i ,peadin r d 20.

o It will be seen that by means 0! this confeet mounted on a rod 18, connected at one end to the sleeve 13 and at its other end to 1 one of a pair of longitudinal liars lllsccuicd at. their rear ends to the lower portion of a a rod 21 secured at its lower end in a sleeve epending port on 49 of the debarrow 42 is connected by a link 46 with an i 1 struetion and arrangement of parts, as here- I t ti y whereof I hereunt y 1 lowered to and raised out of position by means of the driver. that by means of the steering wheel 16 the I driver can control and regulate any irregumovements of the horses. will be seen that. by means of the chain con- ;le\'ers on the frame, the irregu ar draftg movement of the horses will be automatically inheforc described, the harrows will extend ore! and be adapted to operateupon a wide area of ground, and that they can be readily It. will also be seen lar movement in the passage of the culti valor over the ground, due to the irregular I urthermore, it

nections of the whiflle trees with the pivoted regulated. The U-shaped frames 9. and 8 are braced by means of diagonal brace rods 50. When it is desired to use the cultivator. for sowing wheat the barrows maf be readily detached and drills be sccurec to the depending portions 34 and 49 of the arms 7 and 20.

ny means ofthis improved cultivator the ground mav be cultivated late in the season, so as to hold moisture and increase the yield of corn and put the ground in line shape for wheat. By means of this invention a large number of acres of ground can be cultivated in one day by one man with three horses,

and a great saving in time and labor and ex 701180 obtained.

l-laving described the invention, I claim:

A cultivator of the character described comprisin a frame, said frame consisting of a pair of longitudinal bars, a U-shaped frame secured to the forward ends of said bars, said U-shaped frame comprising a transverse bar havin at each end a depending rod bent at its l ower end to provide a stub-axle, and a third depending rod inter-T; mediate the ends'of said bar, a second U-; shaped frame mounted on said longitudinal; bars intermediate their ends and provided} with depending rods at each end, and one intermediate its ends. a forwardly extending wheel frameprojecting from each of the endl rods, said wheel frames en aging the stubaxles of the tirstmanied iii-shaped frame, guide rollers in the forward ends of said wheel frames, wheels mounted in the wheel? frames, a pair of horizontal bars supported? intermediate their ends by the central de- I pending rod of the first-named U-shapedi frame and secured attheir rear ends to g the central dc ending rod of said second? mentioned U-smped frame, said bars provided with guide rollers. barrows secured E to the depending rods of the second men-' tioned U-shaped frame, adjusting means fort said barrows carried by the last named frame draft means carried by the firsts; named U-shaped frame and engaging said ide rollers and steering means for said tame.
